Description

This application is a continuation of International Application PCT/JP2006/315458, which in turn claims priority from Japanese Application No.: JP2005-364253.

TECHNICAL FIELD

The present invention relates to a rain and snow protection device that provides protection from rain and snow that adheres, for example, to the window glass on the driver's seat side of the vehicle and restricts the visibility range, so that a satisfactory field of vision can be continuously visible.

BACKGROUND TECHNOLOGY

Conventionally, the rain that adheres to the window glass, for example, on the driver's seat side of the vehicle, is removed by the action of the wipers. The wiper motion constitutes a back-and-forth motion that moves up and down or left and right in circular fashion. The clear field of vision with no adhering rain can only be seen intermittently. Moreover, at the time the wiper removes the rain, it crosses in front of the driver's eyes, and obstructs the view. The length of the wiper, in order to remove the rain adhering to the window glass, needs to be about ½ the length of the width of the window glass. The rain is also removed across the section of the field of vision that is not necessary for driving safety. The field of vision of the window glass is desirably wider in the sidewise direction, but in the up and down direction, it is adequate to guarantee a field of vision that is wide in the bottom section and rather wide in the top section, with the horizon as the center.
In Japanese Patent Publication No. 2003-291786, a nozzle is positioned in the bottom section of the windshield of the automobile, and rainwater is scattered by blowing compressed air on the face of the glass while this nozzle is moved up and down. However, the rod to which the nozzle is attached crosses the field of vision and scatters only the part of rainwater on which the compressed air is blown, so the range is narrow, and the field of vision cannot be continuously visible. In Japanese Patent Publication No. 2001-26258, the structure is such that the air taken in from the space between the hood and the engine housing of the vehicle is blown on the entire face of the glass from the jet nozzle provided on the front face of the windshield. However, only the rainfall and the water drops near the jet nozzle can be removed. In Japanese Patent Publication No. 10-211869, compressed air and wind pressure during vehicular motion are utilized, but with air from the position of attachment of this air wiper, snow and water drops cannot be removed from the entire face of the glass.

DISCLOSURE OF THE INVENTION

Problems to be Solved by the Invention

The rain and snow protection device blows away the rain so that the rain cannot adhere to the window glass (lighting material) in the visibility range from the driver's seat of the vehicle, and a satisfactory field of vision is thereby continuously visible without the use of wipers. The principles used here are that one sheet or a plurality of sheets of transparent glass (rain protection plates) facing the lighting material are provided on the outside of the vehicle with spaces between. Air having pressure stronger than the wind force exerted at the time of vehicular motion is blown out from the air jets provided inside the vehicle through the spaces in the transparent glass, and is blown continuously from the leading edge of the transparent glass toward the transparent glass and the window glass. The lengths of this transparent glass relative to the lighting material are shortened stepwise with increasing distance from the lighting material. Either of the side edges of this transparent glass is joined to either of the side sections of the window frame or can undergo sliding and/or moving motion. Furthermore, the air comprises, for example, air inside the vehicle, compressed air, exhaust gas from the engine of the vehicle, or exhaust gas from the hydrogen engine (hereinafter, termed air). The purpose is to provide, in this way, a rain and snow protection device whereby the vehicle can move during rainfall, while a satisfactory field of vision is continuously visible.
The present invention provides as its solution to the problems, protection from rain and snow that obstruct the field of vision by adhering to the window glass, for example, on the driver's seat side of the vehicle, so that a satisfactory field of vision can be continuously visible.

BEST WORKING MODE OF THE INVENTION

Therefore, according to first embodiment of the present invention, a rain and snow protection device, is constructed so that a plurality of transparent rain protection plates 11, 12, 13 are provided on the outside of the motor vehicle toward the lighting material 1, in the direction downwards from the top edge section 3, or upwards from the bottom edge section 4, of the window frame 2 of the motor vehicle, ship, or aircraft (hereinafter termed vehicle) in which the lighting material 1 is inserted, wherein the faces of the plurality of transparent rain protection plates 11, 12, 13 are provided therein with spaces 17, 17 facing the lighting material 1 to form by this means the rain protection slits 18, 18, at the leading edges 15, 15 of the aforementioned rain protection plates 11, 12, 13, wherein the lengths of the aforementioned rain protection plates 11, 12, 13 relative to the lighting material 1 are shortened stepwise with increasing distance from the lighting material 1, wherein either of the side edges 14, 14 of the aforementioned rain protection plates 11, 12, 13 is joined to either of the side sections 5, 5 of the window frame 2, furthermore, wherein air jet nozzles 8, 8 are provided at one location or a plurality of locations inside the vehicle, wherein the air 47, 47 blown out from these air jet nozzles 8, 8 passes through the aforementioned spaces 17, 17 and is blown out from the aforementioned rain protection slits 18, 18.
FIG. 1( a) is the figure showing the rain and snow protection device of the present invention 1, as one example of the working mode. Three transparent rain protection plates 11, 12, 13 are provided on the outside of the motor vehicle toward the lighting material 1, in the direction upwards from the bottom edge section 4 of the window frame 2 of the vehicle in which the lighting material 1 is inserted. The faces of the respective transparent rain protection plates 11, 12, 13 are provided therein with the respective spaces 17, 17, 17 facing the lighting material 1 to form by this means the rain protection slits 18, 18, 18 at the leading edges 15, 15, 15 of the rain protection plates 11, 12, 13. The lengths of the rain protection plates 11, 12, 13 relative to the lighting material 1 are shortened stepwise with increasing distance from the lighting material 1. Either of the side edges 14, 14 of the rain protection plates 11, 12, 13 is joined to either of the side sections 5, 5 of the window frame 2. Furthermore, the air jet nozzles 8, 8, 8 are provided at 3 locations inside the vehicle.
FIG. 1( b) is the cross-sectional view along the AA line in FIG. 1( a) of the present invention 1, and shows the principles of the rain and snow protection device. As shown by the arrows, when rain falls on the faces of the lighting material 1 and the rain protection plates 11, 12, 13, air, having strong enough wind force so that the rain cannot adhere on the faces of the lighting material 1 and rain protection plates 11, 12, 13, is blown out from the air jet nozzles 8, 8, 8 provided inside the vehicle. This air passes through the spaces 17, 17, 17 and is blown out from the rain protection slits 18, 18, 18 provided at the leading edges 15, 15, 15 of the rain protection plates 11, 12, 13. The rain is blown away by the strong force of the wind blown out towards the rear and towards the top, along the faces of the lighting material 1 and the rain protection plates 11, 12. There can be protection from the adherence of rain on the faces of the lighting material 1 and the rain protection plates 11, 12. The effects of the action are enhanced by the addition of the speed of motion of the vehicle to the high wind speed that blows upwards towards the rear and towards the top from inside the vehicle in high speed motion. Consequently, a satisfactory field of vision can be continuously visible through the parts of the lighting material 1 and the rain protection plates 11, 12, 13 where no rain has adhered.
The configurations of the rain protection plates 11, 12, 13 of the present invention 1 can have various forms to match the configuration of the face of the lighting material 1. The number of attached sheets of the rain protection plates 11, 12, 13 and the spaces of the rain protection slits 18 can be changed according to the size of the lighting material 1. The leading edges 15, 15, 15 of the rain protection plates 11, 12, 13 are not restricted to being linear in the horizontal direction. The configuration is satisfactory as long as a good field of vision is visible in the driver's line of sight. By treating both faces of the glass with a water-repellent process or a process preventing adhesion, the surface water on the lighting material 1 and the rain protection plates 11, 12, 13 is blown away more easily. Further, a nozzle for spraying liquid may be provided inside the vehicle. Water or wash liquid can be sprayed into the air passing through the inside of the spaces 17, 17 to wash the surfaces or the inside faces of the lighting material 1 and the rain protection plates 11, 12, 13. By heating the air that is blown out, the lighting material 1 and the rain protection plates 11, 12, 13 are heated. The water can be evaporated more easily. It is also possible to provide a wire member for use as heating wire in the lighting material 1 and the rain protection plates 11, 12, 13. When air is not being blown out from the air jet nozzles 8, 8, the opening of the rain protection slit 18 faces upwards so there is incursion of rain and snow into the space 17. However, by providing a drain hole inside the vehicle that can optionally open and close, the water can be drained out. The materials for these rain protection plates 11, 12, 13 comprise transparent materials such as glass and plastic that are identical to those for the lighting material 1.
FIG. 2( a) is the figure showing the rain and snow protection device of the present invention 1, attached to the window frame at the rear of the vehicle, as one example of the working mode. Two transparent rain protection plates 11, 12 are provided on the outside of the vehicle toward the lighting material 1, in the direction downwards from the top edge section 3 of the rear window frame 2 of the vehicle in which the lighting material 1 is inserted. The faces of the respective transparent rain protection plates 11, 12 are provided therein with the respective spaces 17, 17 facing the lighting material 1 to form by this means the rain protection slits 18, 18 at the leading edges 15, 15 of the rain protection plates 11, 12. The lengths of the rain protection plates 11, 12 relative to the lighting material 1 are shortened stepwise with increasing distance from the lighting material 1. Either of the side edges 14, 14 of the rain protection plates 11, 12 is joined to either of the side sections 5, 5 of the window frame 2. Furthermore, air jet nozzles 8, 8 are provided at 2 locations inside the roof.
FIG. 2( b) is the cross-sectional view along the BB line in FIG. 2( a) of the present invention 1, and shows the principles of the rain and snow protection device. When rain falls on the faces of the lighting material 1 and the rain protection plates 11, 12, as shown by the arrows, air having strong enough wind force so that the rain cannot adhere on the faces of the lighting material 1 and rain protection plate 11, is blown out from the air jet nozzles 8, 8 provided inside the roof of the vehicle. This air passes through the spaces 17, 17 and is blown out from the rain protection slits 18, 18 provided at the leading edges 15, 15 of the rain protection plates 11, 12. The rain is blown away by the strong force of the wind blown out towards the rear and towards the bottom, along the faces of the lighting material 1 and the rain protection plate 11. There can be protection from the adherence of rain on the faces of the lighting material 1 and the rain protection plate 11. Consequently, the driver can have a line of sight through the rear window, of a satisfactory rear field of vision continuously visible through the parts of the lighting material 1 and the rain protection plate 11 where no rain had adhered. The rain protection plates 11, 12, 13 are attached facing downwards. The rain protection slit 18 has its opening facing downwards.

The lengths of the rain protection plates 11, 12, 13 relative to the lighting material 1 are shortened stepwise with increasing distance from the lighting material 1. Either of the side edges 14, 14 of the rain protection plates 11, 12, 13 are joined to either of the side sections 5, 5 of the window frame 2. Furthermore, the air jet nozzles 8, 8, 8 are provided at 3 locations in the roof.

Potential for Industrial Utilization

As described above, in the rain and snow protection device of the present invention, the window of the vehicle has no operating parts such as wipers. The attachment can be made at almost the same angle as the lighting material. Therefore, the shape is such that air resistance during motion is considerably reduced. Externally, only the superposition of the transparent rain protection plates on the lighting material is visible on the outside of the vehicle. The plurality of rain protection plates provided with spaces have the effect of absorbing impact toward the colliding object. Moreover, by using a high performance blower to cope with the large amount of rainfall when the vehicle moves at high speed, the rain and snow protection device is suitable for use instead of wipers.
